Cydia

In December last year, Anthony covered a Jailbreak tweak called Always On Proximity, which allowed you to enable and disable the proximity sensor on demand, allowing you to use this feature in a different manner.

When combining this feature with a product by TwelveSouth called SurfacePad, you can finally get that Smart Cover action on your iPhone and not just your iPad.

Obviously this little trick will require you to have a jailbroken iPhone and Always On Proximity installed. Then apply the SurfacePad cover as normal and Voila, you now have a Smart Cover that performs just liked the iPad.

Of course this same method can be applied to nearly any case/cover that folds over the front screen, thus utilizing the proximity sensor. Word on the street however is that the SurfacePad is the way to go.

Always On Proximity is good, but if you are using an exchange account like me where you don't have the option to turn off auto lock, it's useless, once your iPhone is locked by itself, you have to unlock it manually of course if its locked Always On Proximity don't work.

For those with that problem with an exchange account with auto lock, I just discovered an application on Cydia called Exchance Unlock and it turn the auto lock off, in that way Always On Proximity works.
